. Be it known that 1, WILLIAM W. BEWsIo,

a citizen of the UnitedStates, residing at Newark, in the county of Essex and State of New Jersey, have invented a certain new and useful Improvement in Processes of Producing Bias Goods, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

My invention relates to the production of bias goods, such as in binding, tape'and the like, and has for its object" tofurnishaprocess for producing such goods whereby a great saving of time and labor may beaccom lished with little or no waste of material. T e invention further. contemplates the accomplishment of the above results with the production of a strip of any desired length that shall be free from seams.

Prior to my invention, the ordinary not universal, manner for producing bias g'eods, whether for binding or other purposes, was to fold the cloth back and. forth into a number of thicknesses, cut across the width 01' the goods, at the desired angle (about 45 de greesfand afterwards sewtogether the sel-' 'vag'e edges of the se arate pieces thus pro -duced. In making t e firstand last cuts, a

relatively large piece of material is lost from each thickness of the cloth. I Furthermore, in cutting through the pile of folded material,

it is practically impossible to make each must be added the loss'which occursin making .the firstvand last cuts from, the folded cloth or bolt. Aside from'the loss of time which is necessary in order' to trim the stri to uniform Width, a further lossiis incurred by the necessity of, openin up each seam be tween adjacent pieces in t e stripin order to iron the same flat.

It is the object of my invention to produce bias strips in any desired length" with prac I rial from which the bias strip is to be protically no loss of material and with a greatin time and'labor. =To accomplish savin A this, form a bolt or other quantity of mate- Specification of Letters Patent.

As a modification of this man- Patented Jul 14, 1908.

the same by means of an adhesive strip, or,

formed, a spiral out is made around the A convenient manner of accomplishing this I result is illustrated in the drawings, wherein Figure 1 represents an elevation, partly in section, of an apparatus for carrying out my process, and Fig. 2 re resents a sectional view on the line 22 of ig. 1L

Describing the parts by numerals,'1 represenis an arbor having a spiral groove 2 form: d therein, the pitch ofsaid groove corresponding to the direction of the out which it is proposed-to make in the goods. This arbor is supported in a frame 3; and has mounted tl ereon a cylindrical drum 4, said drum being rotatably mounted upon the' shaft and being provided with one or more lugs or projections'5 extending into the spiral groove whereby, on rotation of the drum, it

is caused to move longitudinally of said shaft. The drum may be provided at one end with a flan ed pulle 6 driven by a belt 7 mounted fey or drum 8 which may beon a ong pul driven from any suitable source of power. 9 represents a fixed 'c utter of any approved type mounted in operative relation to the drum 4., The-tube 10 is mounted on the,

, 9 so that said knife can engage the end of the tube which is secured to the forward end of the drum. With this arrangement of parts,

it will be apparent that, when the long pul ley 8 is rotated, drum 4 will also be rotated,

will travel along its shaft 1 and the knife 9.

will out therefrom a continuous bias strip 1 1.

By using a suitable number of knives 9, ap-

propriately spaced, a number of bias strips may be cut from the bolt 10 at the same op' eration. As the distance between adjacent knives may be fixed and as the pitch of groove 2 ill be uniform, it will be apparent that any number of bias strips of uniform width and of practically any desired length may be produced from the tubular body mounted on the drum.

While, for the production of bias goods on a large scale, it is preferable to support the tubular body on a cylindrical drum, it is apparent that a continuous bias strip may be formed from the body, even though the same may not be mounted on such cylindrical drum. be cut by hand by merely marking on the goods with pencil the direction of the out. By following this line, a large quantity of bias goods can be produced by an operator using a pair of shears or other cutter; or the body may be placed on a board which may be elliptical in section and, after having been marked in the manner described, the bias strip maybe cut by means of a knife.

It will be apparent that, by employing a tube or body formed by weaving the goods together and cutting-the same in the manner described, a bias strip may be produced having no seam whatever therein, the length of such strip depending merely upon the length of the tube which is formed from the material.

WVhile, for convenience of description, I have referred to the body as a "tubular body, I do not propose to be limited to cutting the goods from a body which is circular in cross section, and my process of producing the bias strip may be carried out by simply uniting or securing in juxtaposition the edges of the material from which the bias is to be cut and by cutting the same at the desired angle with respect to the axis of said body, notwithstanding the particular cross section For instance, the strips may season which the body may possess during the cut ting operation.

When the strips are cut from a tube which is produced by weaving the goods, it will be apparent that no scams will be formed. in the strip cut therefrom, and the length of the seamless bias strip is limited only by the length of the tube. The prmluction of a seamless strip not only accomplishes a great saving of time which has been heretofore expended in sewing together individual pieces spect to the aXis of the tube to produce a bias effect in the strip thus cut from the tube. 2. The process of producing a bias strip for trimmings, tape, binding and the like which consists informing the textile fabric from which the strip is to be cut into a tube, mounting the same upon a rigid support, which support is adapted to rotate and move in a longitudinal direction, and by means of a suitable instrument making a continuous cut around said tube at a constant angle with respect to the axis of the tube to produce a bias effect in the strip thus cut from the tube. In testimony whereof, I hereunto atlix my signature in the presence of two witnesses.
